If its any help to anyone, here is the write-up from the service writer on my engine failure when I got the repaired bronco back. I will also add to my original thread. Should be attached as an image / I only chopped off my personal info at the top.

They didn't replace both Turbos?!? WTF. Predict RH turbo failure in your future... There is no way that only the LH turbo was the only one affected by the metal debris. That's some bullshit.

Ford's full of crap. I'm probably gonna bail.
Let's say the engine lasts to 10k or even 20k miles !, what good is the warranty going to do me when I'm 200+ miles from home and dealer?

Would it? I mean I'm assuming the oil filter did its job and kept the metal shavings from going back into circulation.

It doesn't even mention replacing oil coolers or anything.

Now of course it's possible that it's just bad follow-through, but I would hope that they would disconnect oil lines to see if any traces of metal were found and replaced those components. So maybe Only metal shavings were found in the one turbo.

My understanding is that the turbos on the 2.7 are mounted to the heads, there wouldn't be cross contamination from one side to the other in this arrangement other than the oil or intake side.

Because exhaust goes from cylinders to exhaust manifold to turbine to exhaust piping therefore if shrapnel occurs due to catastrophic failure in the cylinder - some of it is likely to make it through some of that exhaust system, not just fall into the crank case oil.
I didn't think the exhaust manifold were connected, now I could see issues downside like catalytic converters.

Now I'm not disagreeing. I would want the entire engine, turbos, oil cooler, just about everything else replace.

I'm just saying, I could see where someone could inspect and not find oil shavings on the other side of the engine.

I deleted my comment cause I had a pre-coffee slow moment, lol. Being a v6 only the turbo on the affected cylinder side would likely be affected anyways - as long as contamination didn't make it through the oil. If so I would certainly want all that replace anyways to be safe.

Do you know how little metal it takes to cause problems with standard turbo bearings? Unless these are ball bearing turbos, in which case, I would be less concerned.

I did misread the initial report which referred to metal debris found in the turbocharger itself as opposed to the turbo oil lines.

Still the debris caught by the oil filter would have me very concerned about potential contamination of the oil and thus the turbo bearings. Hopefully they flushed the entire oil system.

I agree But if an oil filter can't filter out metal chunks/pieces, That's a pretty sucky ass oil filter. I mean really .... it has 1 Job ;)

My pool filter takes out algae...i would hope an oil filter would catch even the smallest piece of metal. Of course the bigger chuncks won't ever make it past the oil pump screen.

I'm not a Ford fanboy and this is only the 2nd Ford I've ever owned. This is definitely a real problem and total bullshit to even have to worry about it on a new vehicle. That said, there are literally tens of thousands of these on the road now. 2.7 is by far the more popular engine choice.
I have the 2.7 in my f150 and have ABUSED it and had no issues yet. Currently at 125k. However, I wonder why Ford redesigned the 2.7 for the Bronco??🤔

Mileage doesn't guarantee anything, the build date is more important. With a 21313 motor, you aren't in the danger zone. My 21180 on the other hand is... but still not predictable at all.

Over 13k miles, but don't know whether or not to trust it.

@Snowdogyyz maybe we can get more updated information here?

The other tracker thread has been slowed down, no updates since earlier this month. Anyone have any updates from the last month?

One update, I have passed 34,000 miles, so I suspect that I am in the clear...
